WOVEN-WIRE MATTRESS.

Specication of Letters Patent.

Patented Jan. 15, 1918 Appli-cation led December 29, 1916, Serial No. 139,629.

To all whom t may concern:

Be it known that I, RUDOLPH COOPER- SMITH, of the city of Toronto, in the county of York, in the Province of Ontario, Carr ada, have invented certain new and useful Improvements in W'oven-VVire Mattresses, of which the following is'the speciiication.

My invention relates to improvements in woven wire mattresses andthe objectzof the finventionis to devise in V.that class of. matthe metal strip to the mattress frame and means passing through the perforations and co-acting with woven wire extending from the mattress section edge whereby the mattress section is connected to the metal strip as hereinafter lmore particularly explained by the following specilication.

The ligure represents a plan view of the central portion of a mattress and frame showing the opposing portions of the mattress section, the longitudinal metal strip interposed therebetween and the means by which the mattress sections are connected to such strip.

1 and 2 indicate portions of the end bars of a mattress frame. 3 and 'l indicate supplemental bars secured to the mattress frame and over which the ends of the mattress sections are stretched. 5 and 6 indicate the inner edge portions ot two mattress sections.

In the drawing I have only shown two spiral strands 7 and 8 of each section, each formed of a plurality of wires which form the extreme inner edges oi' the mattress sections. The inner edges of the mattress sections are spaced apart as indicated. Interposed between these sections is located a band of spring metal 9 extending longitudinally of the mattress frame. 10 and 11 indicate a series of perforations located in each edge of the strip 9. 12- and 13 indicate two pair of spiral lsprings connecting the ell-ds of the strip 9 t0 the bars 3 and d. The `inner ends ot' the springs 12 and 13 are preferably passed through the end perforation of eachseries `of perror-ations 10 and 11 in order to-connect the springs to the. stript). Theropposite ends olf the springs 12 and 13 passthrough `perfoiations 11 formed in each of the bars 3 and Il.

15 and. lindicate single spiral wires ot' the same pitch as the splralwires forming the mattress. The wires 15 and 16 Y.are threaded through the inner edges of Vthe multiple wires 8 forming the `extreme inner edge oli' each mattress section. 17 and 18 indicate spiral wires also ont the same pitch as the wires forming the mattresssections.

The `wires 17 and 1S are threaded through the pertorations 10 and 11 as indicated. 19 and 2O indicate wires similar to the wires 1'? and 18 which are threaded through the wires 17 and 18 as indicated, the inner edges of such spirals overlapping the opposing edges ot the spirals 15 and 16, the spirals of the wires 19 and 20 being intermediate of the spirals of the wires 15 and 16. 21 and 22 indicate stitl' reinforcing wires. The wires Q1 and 22 are passed longitudinally through the overlapping portions of the wires 19 and 15 on one side oi' the strip 9 and the wires 20 and 16 on the other side oie the strip 9 thereby connecting the wires 19 and 15 and 20 and 16 together and consequently the inner edge of each mattress section 5 and 6 to the center strip 9. The ends of the wires 21 and 22 are passed through the spiral springs 12 and 13 at each end of the strip 9. The ends ot' the wires 17 and 19 are wound around the reinforcing wire 21. The ends ofthe wires 1S and 2O are wound around the reinforcing wire 22. By this means a permanent connection is provided betweenthe center strip 9 and the inner edges ot' the mattress section.

Although I have only described this invention in connection with the center strip it will, of course, be understood that a strip similar to the strip 9 may be provided at each mattress section outer edge to which the mattress section outer edge is similarly connected.

When making' up this mattress the sections 5 and 6 are tirst stretched upon the mattress frame thereby slightly increasing the pitch between the coils of the woven wire. The distance between the perforations 10 and 11 is made to correspond to the pitch ot the woven wire of the mattress sectionafter is stretched and the spiral connecting wires connecting the inner edges of the mattress section to the center strip are also made to correspond in pitch to the distance between` the perforations so as to allow of an even stretch in the mattress from end to end when in use.

From this description it will be seen that I have devised a very simpleform of connecting means between the independent sections of a woven wire mattress and which will serve to support the longitudinal edges of the mattress section so that they will not give and allow the mattress t0 sag either in the center or at the outer edges thereof so that when the mattress is in use the center of each section takes un the sag and therefore insures that they operate independently.

.. What I claim as my invention is- 1. In a woven wire mattress, the combina- .tion with the mattress frame and mattress section supported thereby, of a metal strip extending longitudinally parallel with the mattress edge having a series of edge perforations, resilient means for connecting the ends of the strip to the mattress frame, a spiral wire woven through the edge perforations of the strip, and interengaging means between the spiral wire of the strip and the parallel edge wire of the vmattress section.

2. In a woven wire mattress, the combination with the mattress frame and mattress section, of a metal strip extending longitudinally and parallel with the edge of the mattress section and having a series of edge perforations, a woven wire portion engaging with such edge perforations, a woven wire portion carried by the edge of the mattress section overlapping the woven wire portion extending from the strip, and a longitudinally extending reinforcing wire threaded through such overlapping portions.

3. In a woven wire mattress, the combina- Y tion with the mattress frame and mattress section, of a metal strip extending longitu- VYdinallyY and parallel with the edgeof the mattress section and having a series of edge perforations, a woven wire portion engaging withsuch edge perforations, a woven vwire portion carried by the edge of the mattress section overlapping the woven wire portion extending from the strip, a longitudinally extending reinforcing wire threaded through such overlapping portions, and spiral springs connecting the ends of the strip to the mattressY frame and through the convolutions of which the ends of the reinforcing wire extend.

4:. In a woven wire mattress, the combination with the mattress frame and wire mattress section supported thereby, of a metal strip extending longitudii'ially. parallel with the edge ci the mattress` section andhaving a series of edge perforations, resilient means of the stretched` mattress section, resilient means for connecting the ends ofthe strip to the mattress frame, woven Vwire spirals engaging the perforations of the strip. a woven wire spiral extending through the spiral of the edge wire of the mattress section, and interengaging means for connecting the spiral passing through the edge wire of the mattress section and the spiral wires passing through the perforations of, Vthe strip.
